Despite being only 18, Romero can hold his own physically and score with both feet. He bagged braces in Velez’s first two 2017/18 Primera Division matches, immediately vanquishing fans’ concerns about the departure of principal goalscorer Mariano Pavone.

Romero believes only ligament damage put paid to Arsenal’s pursuit of him last year.

Highlight so far: El Tigre undid Tigre in the opening round of Primera Division action in August, with a stretching volley and violent rocket spurring Velez to a 3-0 away win. MW

Need to know: “Alexis Sanchez knows his name now,” remarked Jose Mourinho after Tuanzebe, on his Premier League debut, kept the Chilean in handcuffs.

The teenager played right-back that day, but excelled in central midfield at the end of 2016/17 and was invariably a ball-playing center-back for United’s youth sides.

Born in Congo but raised in Rochdale, Tuanzebe joined United’s ranks as an eight-year-old, gave his first television interview aged 11, and in 2015 became the maiden first-year scholar to captain their U18 side since Gary Neville in 1991.

Highlight so far: Tuanzebe’s top-flight bow may have ended in a 2-0 defeat at the Emirates, but his display made him the talk of Twitter and Sanchez the subject of some unflattering hashtags. MW

33. Ben Woodburn (Liverpool)

Need to know: Woodburn has been likened to former Liverpool strikers Robbie Fowler and Michael Owen since making his professional debut last year, but it’s still not clear whether he’ll go on to play through the middle – the Welshman has spent much of his early career operating from the left.

Regardless of his future position, Woodburn is a wonderfully gifted youngster who packs a range of exciting attributes including speed, intelligent movement and clinical finishing.

He became Liverpool’s youngest ever scorer when he netted at the age of 17 years and 45 days against Leeds last season.

Highlight so far: How about bagging a second-half winner from 25 yards on your full Wales debut? Woodburn made the perfect impact against Austria to keep the Dragons’ hopes of qualifying for the 2018 World Cup alive. Alas, however, the youngster will have to wait for a taste of tournament action. GL
